Sunset Overdrive developer, Insomniac Games, has tweeted out a couple times this week, stating that it would like to bring the game to Windows 10, however, it is up to Microsoft's Xbox division to make the call on whether to bring the game to Windows 10.
we'd love it if it could happen but ball is in Xbox's court on it

Now, a spokesperson for Microsoft has reached out to GameSpot to say that the company is "proud" of the game, calling Insomniac Games a "great partner" and that they "love working with them," however, when asked if Sunset Overdrive would be made available for Windows 10 in the future, the response was the standard non-answer:
We have no further news at this time.
So, for fans of Sunset Overdrive or PC gamers wanting to get ahold of it, there's no news on when, or if, the game will arrive on Windows 10 PCs at this time.
